Title: Reactive power compensating device
Inventor: KOHAMA MINORU
IPC: G05F1/66
Filed: 1986-02-14
Abstract: PURPOSE:To suppress the fluctuation of the voltage of the power receiving end of an AC power source, which is caused by a rush current flowing in a load right after a load is entered, without a control error by operating a 2nd detection circuit until the load attains a stable state right after it is entered and operating a 1st detection circuit after the load reaches a stable state. CONSTITUTION:A detection circuit 22 detecting a current IL flowing to the load 4 or its reactive power, a detection circuit 24 detecting the voltage VS of the power receiving end 6 of the AC power source 1, and a switching circuit 25 selectively operating both detection circuits 22 and 24 are provided. Until the load 4 attains a steady state right after a circuit braker 2 is applied, the detection circuit 24 is operated. After the load 4 reaches a steady state, the detection circuit 22 is operated. Thus the fluctuation of the voltage VS of the power receiving end 6 of the AC power source 1, which is caused by the rush current flowing in a load transformer 3 right after the circuit braker 2 is applied, can be suppressed without a control error.

Title: Record player system
Inventor: TAKIZAWA KAZUYUKI
IPC: G11B3/095
Filed: 1978-03-17
Abstract: PURPOSE:To enhance the protection characteristic of stylus tip as a rest position detector moves a driving device backward to lift the tone arm when the tone arm is manually returned to the arm rest on the way of record playing in a fully automatic player system. CONSTITUTION:When a tone arm 5 is returned to the arm rest 13 position on the way of record playing, the arm rest position is detected with an arm rest detector, then a tone arm driving motor 8 runs backward. This causes the control cam to be run backward to automatically reset the tone arm driving device 25 and move it backward so that the next lead-in operation may be performed. At the same time, a cam 38 for arm lifter also turns to raise a lifter shaft 60 which in turn lifts an arm lifter 12 to lift the tone arm 5. Hence, even if the tone arm is accidentally removed from the arm rest 13, the arm 5 will no longer fall onto the turntable.

Title: Ceiling fan
Inventor: INAZUMI HIDEYOSHI
IPC: F04D25/08
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a ceiling fan comprising each blade stopping part simply inserted in and locked on to a holder, in which each blade is mounted to a rotor, without being screwed in and locked on. SOLUTION: When a blade is to be inserted so as to be mounted, the insertion of the blade 6 into the inlet of a holder 2 thereby allows the inserted end 61 of the blade 6 to abut against the abutting surface of an engaging body, and to push back the engaging body 25 upward, and concurrently, the blade 6 can be fixed thereto by letting the fit-in part 27 of the engaging body 25 be dropped in and fitted in a holding part 63 at the position where the blade has been completely inserted. When the blade is to be taken out, the engaging body 25 can be pushed back upward by letting a pin 28 be pressed and pushed in the inside of the holder 25 against the energizing force of a spring 29, so that the fit-in part 27 of the engaging body 25 is thereby separated from the holding part 63 so as to allow the lock of the blade 6 to be released.  By this constitution, the blade 6 can freely be pulled out from the holder 2, and can thereby be taken out.

Abstract: PURPOSE:To judge the operating state of the power supply of an external accessory device with one monitoring signal by judging the on and off states of a means for supplying electric power to the external accessory device with an output signal state at the time of stopping a cooling means cooling the external accessory device. CONSTITUTION:When a main body device 500 is started to use, a main body control means 302 retrieves the fact that each unit is in a normal state. In the external accessory device (A) 10, its state is detected via an interface 16 and a communicating means 14. When the external power 11 of the external accessory device (A) 10 is supplied, a fan 12 is normally rotated so that a detecting means 13 detecting the stop of the fan outputs a detection signal S1 showing that the fan is under a normal rotation. When the rotation of the fan 12 is stopped in an initial state or in the process of an operation, the waveform of the detection signal S1 is observed by a specific time T to detect the fact that the state of the external power 11 is turned on or off. In other words, two fault modes can be detected with one abnormality monitoring signal.
